Optimal Design Of Green Roofs: Mathematical Model And Experimental Evidence, Jing Hong

Theses and Dissertations

Green roofs ease the heat island effect and decrease stormwater runoff. Optimizing green roof design helps achieve these goals more efficiently. This dissertation proposes energy and mass models of green roofs and validates them through experimental evidence.

The energy and mass transfer models proposed in this dissertation can be programmed in any simulation tools, and benefits architects and engineers optimizing their green roof design. The mathematical models of green roofs were validated by the measured soil temperature and water content of the Golda Meir Library green roof.

Using energy and mass balance models, this research found the effects of the …

The Concept Of “Green Roofs” In Tirana, Eduina Zekaj, Franceska Delia

UBT International Conference

The term “green roof” is a pretty old concept in the history of Architecture, and it begins since prehistoric times with attempts of our ancestors to cover up their housing with greenery. But this term is not well known in Tirana and it is just starting to apply in the new era of projects.

The first attempts started in 2010, but there are very few existing projects that fulfill the construction details that a real green roof needs. First of all, we have to understand why we do need green roofs in Tirana. According to “The Guardian”, Tirana was called …

Green Roof Energy Balances For Native Grasses And Sedum, Chris Schwarz

School of Natural Resources: Dissertations, Theses, and Student Research

Green roofs offer a possible solution to reduce urban heat island effects caused by urbanization. Conventional green roofs use sedum for plant cover but growing evidence suggests native species offer better results for harsher environments. However, more information is needed to understand the potential of native species for green roof use in terms of survivability and cooling potential. This study was conducted from July 2013 through October 2013 to quantify the energy balance components for native grasses and sedum on a Midwestern green roof. The semi-intensive green roof located on the Larson Building parking garage in Lincoln, NE was used …

The Cost Of Design: A Life-Cycle Assessment Of Green Infrastructure Technology, Cheryl Kaye Lough

LSU Master's Theses

Landscape architectural research of green infrastructural practices has increased dramatically over the last decade. Due to this research, many designers are suggesting some form of green infrastructure within their projects. Much of the present-day research focuses on function and not long term impacts of individual materials. The current rate of implementation of green infrastructures might not produce a drastic impact upon the environment, but with installations being realized at an ever-increasing and larger scales, even minute elements within the construction of these structures begin to influence the overall ecological footprint produced by our designs. Designers must re-evaluate the materiality of …

Rethinking Extensive Green Roofs To Lessen Emphasis On Above-Ground Biomass, Richard K. Sutton

Landscape Architecture Program: Faculty Scholarly and Creative Activity

In the future, most green roof applications will not be highly visible, yet these roofs will still provide the benefits of heat island reduction, stormwater control and biodiversity for hard-surfaced cities. However, human bias in wanting more biomass and visible blooms leads green roof horticulturalists and their approach of maximizing those aspects down a slippery slope that, in turn, leads to increased hours of labor, over-watering and fertilizing and specifying too many cultivars

Environmental Monitoring In Preparation For The Installation Of A Green Roof, Andrew N. Martin, Ming Qu

The Summer Undergraduate Research Fellowship (SURF) Symposium

Green roofs are becoming an increasingly popular way to improve the environmental, economic, and aesthetic performance of both new and existing buildings. Along with the green roofs themselves, it is also common to install sensors to measure various environmental parameters that are affected by or important to the operation of the roof such as precipitation, temperature, and runoff. However, for most of these systems, the sensors are installed at the same time or even after the green roof. Therefore, no before-and-after comparisons can be made for those roofs. To account for this missing data, monitoring equipment was installed on a …

Assessing The Green Roof Technology In Green Building Rating Systems, Lee Xia Sheng, Ati Rosemary Mohd Ariffin, Hazreena Hussein

Integrated Sustainable Roof Design, Lee Xia Sheng, Ati Rosemary Mohd Ariffin, Hazreena Hussein

Hazreena Hussein

‘Necessity is the mother of invention’…this proverb is very true with all great inventions that contribute to sustainable development. High density and steep land value have driven people to maximise liveable and productive spaces in urban settings. This include the reinvention of roofs’ functions extending from merely a protection from the elements to a platform housing sustainable building technologies such as green roof, rainwater harvesting and photovoltaic power generation. On one hand, researches or different sustainable technologies are competing for funding, resources, space and recognition. On the other hand, some of the green building rating criteria have immense influence on …

Master Planning Communities With Wildlife In Mind, Helen A. Peebles

LSU Master's Theses

Master-planned communities can be designed for the protection of wildlife while providing an aesthetically pleasing, eco-friendly, and affordable community for people. This study was conceived from a background of academic studies in plant biology, forestry, and landscape architecture, and a desire to rescue wildlife habitat from the encroachment of urban sprawl. A variety of books and periodicals were consulted, along with a few web sites. The primary threats to wildlife habitat are habitat fragmentation, pollution, and exotic invasive species of plants, animals, insects, and diseases. Many aspects of planning are addressed, including wildlife corridors, site selection, connecting habitat patches, and …
